I'm a Freelance Web & Mobile Developer based in Nairobi, Kenya, passionate about building efficient, scalable, and visually engaging digital products. With over 3 years of experience in professional web design and development, I craft premium, responsive websites and dynamic web applications — and as a professional mobile developer I build and ship Flutter applications that are published on Google Play. I specialise in fintech: payment integrations, M-Pesa deposits and withdrawals, and trading and betting platforms that move real money locally and abroad.
Recently, I earned my Oracle Cloud Infrastructure (OCI) certification, expanding my expertise into cloud computing, DevOps, and infrastructure management. This enables me to design, deploy, and manage web applications on the cloud securely and efficiently — combining creativity in front-end design with technical precision in back-end and cloud infrastructure.
